-11 find that, at the temperature stated, the i curing is accomplished in about one-half the f time that is required for curing inthe ordinary manner, the condition of the meat appearing to render it much 'more permeable r by the salt; and where the temperature employed is higher the curing is completed more rapidly. Thus, at 80 l hto 90 F., which temperatures I have employed in the practiceoi my process, the meat cures in about one-fifth the time required for curing it in the ordinary Way; but the permeating action of the saltisthen so rapid that it is liable, even in the weak solution referred to,

4 to produce excessive saltness in the meat, so that it is not-so desirable to employ a higher temperature than 40 F. to F., or there about, in which-to conduct the curing in the comparatively Weak brine. However, the saving of onehalf the time for curing is productive of vast advantage in the Way of economy in time, fuel, storage and inter est, 'andirendering the market for the meat more stable and the article more merchandizable, by removing from it the speculative element in thefluotuation of price due tohaving to carry it for long periods.
